Handheld spectrum analyzers from Rohde & Schwarz facilitate the installation and servicing of both CDMA® and LTE networks
<p>The new R&S®FSH-K46 and R&S®FSH-K46E software options provide all the functions that service and installation technicians need to check the operationally relevant parameters of CDMA2000® base station signals. The R&S®FSH-K46 option measures the power, determines the ratio of peak power to average power, and displays characteristic parameters such as the power in both the pilot channel (F-PICH) and the synchronization channel (F-SYNC), the carrier frequency offset, composite EVM (error vector) and Rho. The R&S®FSH K46E option has been designed for more in-depth analysis and can also perform code domain power measurements. These measurements provide the information needed for graphically displaying the power in all occupied and unoccupied channels, for example. </p>
<p>Additional new measurement functions have been incorporated into the base unit, including the ability to measure spurious emissions that might interfere with the adjacent transmit signal. Predefined masks for CDMA2000®, WCDMA, TD SCDMA, WiMAX™ and LTE allow the user to measure the spectrum emission mask quickly, with minimum operating effort. The gated sweep function makes it possible to display pulsed signals in the spectrum.</p>
<p>Thanks to their expanded demodulation bandwidth of 20 MHz, the R&S®FSH4 and the R&S®FSH8 analyzers are safe investments for the installation and maintenance of LTE networks. Applications for LTE will soon become available, in addition to the applications for 1xEV-DO, 3GPP WCDMA and CDMA2000®. </p>
